Just saw this on Saturday, rushed in mainly as am a huge Aishwariya Rai fan, and generally love her movies (unless movies like Robot waste of her talent, or Mistress of Spices poor storyline which deviated from the novel and bad direction). Also wanted to see Akshay Kumar in flares and the 70′s hair.
I knew this was going to be a fluffy, feel good comedy and it was. Yes the story is convoluted, but the psychedelic trailer and songs should be warning enough that it will be anything but serious. It is a hindi version of the first Back To the Future without any of the annoying villains, bolder clothes, a stronger leading lady, more colour and catchy lively music. I love the song Chhan Ke Mohalla Sara where Mala first appears.
Akshay Kumar as Kishen is funny, there are no side splitting moments (like the chicken chase at the beginning of Singh is King), but this is one of his better comedies. The pseudo villain who can sing in two voices including a female soprano, is unique.
One worth watching in cinema for full enjoyment, expect it to be nonsensical and you won’t be disappointed.

I really liked this movie too, it was quite good and very funny. I especially love the music, its really random LOL.
